I had PMR but wasn't diagnosed yet. (4 years with a rheumy who didn't recognise it.) I had two types of pain and also Crohn's. I had tiny ulcers in my small intestine. The pain was typical PMR when I used my muscles but I also hurt when I didn't move, too. My GI doc didn't believe in LDN but the rheumy PA did so I got it from her. I started with 2mg and in two days my nonmoving pain was gone. In a couple of months my small intestine healed and the ulcers haven't come back. I started using it in May 2019 and my next colonoscopy was normal. I had to stop it in August 2020 when I had my hip replacement (I had to use opiates.) But in 3 weeks I noticed the all over pain was back so I went back to it in a hurry. It worked again. I have stayed on it and I finally got diagnosed in April 2021 so I use both pred and LDN, I am tapering now without incident and don't plan to do without it. I don't know if it will work for you, but it is worth a try. You might at least lower your pred.
